A retrospective, case series study was undertaken to identify magnetic resonance imaging (MRI) characteristics of gliomatosis cerebri in dogs. Fourteen dogs were included by review of histopathological records and contemporaneous MRI. On MRI, all lesions presented as ill-defined, intraaxial lesions within the left and right forebrain hemispheres with involvement of white and gray matter. Lesions presented as hyperintense areas on T2-weighted and FLAIR sequences and as hypointense or isointense areas on T1-weighted images, with mild parenchymal contrast enhancement in three dogs...

Radiologists play a key role in brain tumor diagnosis and management and must stay abreast of developments in the field to advance patient care and communicate with other health care providers. In 2016, the World Health Organization (WHO) released an update to its brain tumor classification system that included numerous significant changes. Several previously recognized brain tumor diagnoses, such as oligoastrocytoma, primitive neuroectodermal tumor, and gliomatosis cerebri, were redefined or eliminated altogether...

OBJECTIVES: Patients with overlapping glioblastomas (former known as gliomatosis cerebri according to the 2007 WHO classification) have a poor prognosis. Most of the patients undergo biopsy to confirm histopathological diagnosis. Treatment comprises chemotherapy, radiation and combination of both. We determined whether resection of the contrast enhancing tumor parts leads to a prolonged survival. PATIENTS AND METHODS: We performed a retrospective analysis and included 31 patients with overlapping glioblastomas (OG) who showed WHO IV in the initial histopathological examination...

Gliomas are the most frequent intrinsic tumours of the central nervous system and encompass two principle subgroups: diffuse gliomas and gliomas showing a more circumscribed growth pattern ('non-diffuse gliomas'). In the revised 4th edition of the WHO Classification of CNS tumors published in 2016, classification of especially diffuse gliomas has fundamentally changed: for the first time a large subset of these tumours is now defined based on presence/absence of IDH mutation and 1p/19q codeletion. Following this approach, the diagnosis of (anaplastic) oligoastrocytoma can be expected to largely disappear...

Gliomatosis cerebri is a diffuse infiltrating glioma of neuroepithelial origin that affects more than 2 cerebral lobes. This is rarely seen in pediatric patients. The clinical presentation and imaging are very unspecific, and a biopsy is typically needed for the diagnosis. Given the widespread nature of the disease, surgical treatment is not possible and has a poor overall prognosis. A pediatric patient presented with elevated intracranial pressure. All initial studies were negative, and the imaging showed a symmetrical affection involving the supratentorial and infratentorial regions...

A recurrent glycine-to-arginine/valine alteration at codon 34 (G34R/V) within H3F3A, a gene that encodes the replication-independent histone variant H3.3, reportedly occurs exclusively in pediatric glioblastomas. However, the clinicopathological and biological significances of this mutation have not been completely elucidated; especially, no such data exist for tumor samples from Japanese patients. We analyzed 411 consecutive glioma cases representing patients of all ages. Our results demonstrated that 14 patients (3...

Bevacizumab has been shown to improve progression-free survival and neurologic function, but failed to improve overall survival in newly diagnosed glioblastoma and at first recurrence. Nonetheless, bevacizumab is widely used in patients with recurrent glioma. However, its use in patients with gliomas showing a gliomatosis cerebri growth pattern is contentious. Due to the marked diffuse and infiltrative growth with less angiogenic tumor growth, it may appear questionable whether bevacizumab can have a therapeutic effect in those patients...

Gliomatosis cerebri is a rare subtype of glioma involving more than three lobes of the central nervous system. Currently, diagnosis of gliomatosis cerebri can be confirmed pathologically, surgically, or with magnetic resonance imaging that shows high-signal areas expanding to the cerebral hemisphere, brain stem, cerebellum, and spinal cord. Although this disease has great clinical importance, it has recently been removed from the revised WHO classification of Tumors of the Central Nervous System (2016) owing to divergence between its morphological features and molecular profiles...

Spinal cord glioma is uncommonly reported in dogs. We describe the clinicopathologic and diagnostic features of 7 cases of canine spinal cord glioma and briefly review the veterinary literature on this topic. The median age at presentation was 7.2 y. Six females and 1 male were affected and 4 dogs were brachycephalic. The clinical course lasted from 3 d to 12 wk, and clinical signs were progressive and associated with multiple suspected neuroanatomic locations in the spinal cord. Magnetic resonance imaging of 6 cases revealed T2-weighted hyperintense lesions with variable contrast enhancement in the spinal cord...

Normal brain cells depend on glucose metabolism, yet they have the flexibility to switch to the usage of ketone bodies during caloric restriction. In contrast, tumor cells lack genomic and metabolic flexibility and are largely dependent on glucose. Ketogenic-diet (KD) was suggested as a therapeutic option for malignant brain cancer. This study aimed to detect metabolic brain changes in patients with malignant brain gliomas on KD using proton magnetic-resonance-spectroscopy ((1)H-MRS). Fifty MR scans were performed longitudinally in nine patients: four patients with recurrent glioblastoma (GB) treated with KD in addition to bevacizumab; one patient with gliomatosis-cerebri treated with KD only; and four patients with recurrent GB who did not receive KD...

BACKGROUND: Gliomatosis cerebri is a rare diffusely infiltrating malignant glial neoplasm. Presenting symptoms include seizures, neurologic deficits, and frequently symptoms related to increased intracranial pressure (ICP). Surgical intervention, including brain biopsy, may induce worsening of these neurologic symptoms. We reviewed our database to identify prognostic and risk factors for perioperative deterioration specifically associated with elevated ICP. METHODS: Between 2006 and 2014, 78 patients were treated for gliomatosis cerebri...

Recurrent high-grade gliomas (HGGs) of childhood have an exceedingly poor prognosis with current therapies. Accordingly, new treatment approaches are needed. We initiated a pilot trial of vaccinations with peptide epitopes derived from glioma-associated antigens (GAAs) overexpressed in these tumors in HLA-A2+ children with recurrent HGG that had progressed after prior treatments. Peptide epitopes for three GAAs (EphA2, IL13Rα2, survivin), emulsified in Montanide-ISA-51, were administered subcutaneously adjacent to intramuscular injections of poly-ICLC every 3 weeks for 8 courses, followed by booster vaccines every 6 weeks...

Gliomatosis cerebri (GC) is a universally fatal extensive and diffuse infiltration of brain parenchyma by a glial tumor. Many aspects of this phenomenon remain unknown. The First International Gliomatosis cerebri Group Meeting had the following goals: refine the clinical and radiologic diagnostic criteria for GC, suggest appropriate diagnostic procedures, standardize tissue manipulation for histologic and molecular characterization, and prioritize relevant preclinical projects. Also, general treatment recommendations were outlined for the pediatric population...
